gitadora: (arena model) single window mode + subscreen overlay (#486)

## Link to GitHub Issue, if one exists #477 ## Description of change This is a work in progress. What works: - [x] subscreen overlay shows the touch screen image (in windowed mode) - [x] touch works in the overlay - [x] only the main window is shown, other windows are not launched What doesn't: - [ ] game occasionally crashes when entering test menu? - [ ] full screen mode is not tested at all due to monitor requirements - [ ] need more polish (various options to control the behavior)
